计算机自适应测验中沉思-冲动型认知风格、能力水平、试题难度与试题作答时间的关系分析

Analysis of the Relationship between Reflective-Impulsive Cognitive Style,Ability Level,Item Difficulty and Item Answering Time in Computerized Adaptive Testing

伴随着教育测量与评价理论的发展,试题作答时间已被逐步纳入被试能力水平的计算模型。因此,在计算机自适应测验中,试题作答时间的影响因素及其关系是否会随正答概率的变化而变化,受到了研究者的持续关注。文章旨在探讨在不同正答概率条件下,自适应性测验中被试的沉思-冲动型认知风格、能力水平、试题难度与试题作答时间之间的关系。通过多组分析模型,文章发现测验环境由难变易时,个体差异与试题特征对试题作答时间的总效应显著减少,这有利于提高测验结果的精确性和有效性,并改善测验的公平性。

With the development of education measurement and evaluation theory,the item answering time has been gradually incorporated into the calculation model of subjects’ability level.Therefore,in the computer adaptive test,the influencing factors of item answering time and whether the relationship between them could vary with the change of the correct answer probability has been continuously concerned by researchers.The purpose of this paper was to explore the relationship between reflective-impulsive cognitive style,ability level,item difficulty and item answering time in computerized adaptive testing with different correct answering probability.Through multi-group analysis models,it was found that when the testing environment changes from difficult to easy,the total effects of individual differences and item characteristics on item answering time were significantly reduced,which was conductive to improving the accuracy and the effectiveness of test results,and thereby improving the fairness of the test.
